- Add binding doc - Add imx91 thermal driver - dts part wait for https://lore.kernel.org/imx/Z04W5chGq5TitB9f@lizhi-Precision-Tower-5810/ merged, so not in this serial. Signed-off-by: Frank Li <Frank.Li@nxp.com> --- Changes in v5: - Add irq support. - change to period mode. - Link to v4: https://lore.kernel.org/r/20241216-imx91tmu-v4-0-75caef7481b8@nxp.com Changes in v4: - Add Kryz's review tag for binding - Add Marco's review tag for driver - Use devm_add_action() - Move pm_runtim_put before thermal_of_zone_register() - Link to v3: https://lore.kernel.org/r/20241212-imx91tmu-v3-0-85e756b29437@nxp.com Changes in v3: - add ref thermal-sensor - restrict #thermal-sensor-cells to 0 only - Change to unevaluatedProperties - add IMX91_TMU_ prefix for register define - remove unused register define - fix missed pm_runtime_put() at error path in imx91_tmu_get_temp() - use dev variable in probe function - use pm_runtime_set_active() in probe - move START to imx91_tmu_get_temp() - use DEFINE_RUNTIME_DEV_PM_OPS() - keep set reset value because there are not sw "reset" bit in controller, uboot may change and enable tmu. - Link to v2: https://lore.kernel.org/r/20241210-imx91tmu-v2-0-5032aad4d88e@nxp.com Changes in v2: - use low case for hexvalue - combine struct imx91_tmu and tmu_sensor - simplify imx91_tmu_start() and imx91_tmu_enable() - use s16 for imx91_tmu_get_temp(), which may negative value - use reverse christmas tree style - use run time pm - use oneshot to sample temp - register thermal zone after hardware init - Link to v1: https://lore.kernel.org/r/20241209-imx91tmu-v1-0-7859c5387f31@nxp.com --- Pengfei Li (2): dt-bindings: thermal: fsl,imx91-tmu: add bindings for NXP i.MX91 thermal module thermal: imx91: Add support for i.MX91 thermal monitoring unit .../devicetree/bindings/thermal/fsl,imx91-tmu.yaml | 79 ++++ drivers/thermal/Kconfig | 10 + drivers/thermal/Makefile | 1 + drivers/thermal/imx91_thermal.c | 422 +++++++++++++++++++++ 4 files changed, 512 insertions(+) --- base-commit: f50e59ef812d87066a5ab07c7bafc54aef378c20 change-id: 20241209-imx91tmu-af2a7c042d8d Best regards, --- Frank Li <Frank.Li@nxp.com>
